In this study, stable PbTiO3 coating solution was prepared using diethanolamine(DEA) complexing agent and deposited on indium-tin oxide(ITO) coated glass substrate. Prepared thin films were dense and crack-free. Perovskite-type PbTiO3 thin films could be obtained above 50$0^{circ}C$, while the films heat-treated above $650^{circ}C$ showed undesired properties due to interface reactions between films and substrates and warpage phenomena of substrates. Measured maximum dielectric constant and loss tangent were found to be 144 and 0.0163 at 1 kHz, 55$0^{circ}C$ heat-treatment, respectively.
